Steps to reproduce:

1. Open the Examples App of https://github.com/mapbox/mapbox-maps-ios, build it on simulator iPad (6th generation)
2. Change the Feature-Location to City Run on the simulator
3. Choose the Display the user's location from Location Examples.

We could see the cpu is running around 56% - 65%. It's related with the mapView rendering with the location update.

According to the comment, is there any way to reduce the redraw of mapView with the location update?
